Starts a multiple-buffer decode operation.
If you use the low-level interface for multiple-buffer
decoding, you must call Start() to begin the decode
operation. You may use a Base64Decoder instance for many
decode operations, but you must call Start() to begin each
operation.
For more information on using the low-level interface, see the overview section for Base64Decoder.
You do not need to call this method if you use the Decode() method for decoding.
